Chemistry and Electrochemistry: Reactions, Osmosis, and Electrodes

This lecture covers various topics in chemistry and electrochemistry, including chemical reactions like the explosive decomposition of nitrogen triiodide, osmosis experiments with saltwater, and electrochemical processes such as copper plating. It also delves into the concept of osmotic pressure, the Nernst potential, and the functioning of a Daniell cell. The presentation explores the principles behind the osmotic cell, discussing the diffusion of water through a semi-permeable membrane and the equilibrium between solute and solvent concentrations. Additionally, it examines the application of electrochemical reactions in a fuel cell, showcasing the oxidation and reduction of hydrogen and oxygen. The lecture concludes with a detailed analysis of the evolution of water in an osmotic cell over time.
